SCB9 dry-type power transformerDetailed product description：

SC9-5~100/10 series epoxy resin cast dry-type power transformer
This series of epoxy numerical casting dry-type transformers are made of high-quality materials with scientific formulas, and are produced using advanced production testing equipment and strict processes. The product has the characteristics of high reliability and long service life. According to different usage environments, different protection levels of enclosures can be configured or no enclosures can be configured. Suitable for important or special environmental places such as high-rise buildings, commercial centers, airports, tunnels, chemical plants, nuclear power plants, ships, etc.


Features:
Safe, fireproof, pollution-free, and can operate directly in the load center.
Adopting German HTT technology, it has high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability, and a long service life.
Low loss, low noise, significant energy-saving effect, maintenance free.
Good heat dissipation performance, strong overload capacity, and can increase capacity operation when forced air cooling is used.
Good moisture resistance, suitable for operation in high humidity and other harsh environments.
It can be equipped with a comprehensive temperature monitoring and protection system. Adopting an intelligent signal temperature control system, it can automatically monitor and display the working temperature of each three-phase winding, and can automatically start and stop the fan,
And it has functions such as alarm and trip settings.  
Small size, light weight, small footprint, and low installation cost.
The iron core is made of high-quality cold-rolled silicon steel sheets, with a 45 degree stepped fully inclined joint structure. The three shear and two punch iron core chamfering and transverse cutting process, as well as the five step step cutting and stacking process, are used to improve the magnetic flux distribution at the joint and reduce the vibration energy of the iron core. The integrated solidification of the iron core and the sealing process with insulating resin on the surface effectively reduce no-load losses, no-load flow, and iron core noise.
The high-voltage coil is made of high-quality F-grade insulated wires and internationally advanced insulation materials. The larger capacity coil is equipped with a heat dissipation duct along the axial direction. This structure has good resistance to current shock, temperature changes, cracking, and excellent heat dissipation performance. Adopting a multi-stage segmented cylindrical structure, it has a strong ability to withstand overvoltage and a very low level of partial discharge. The coil mold is vacuum dried and then poured,
The entire pouring and curing process is completed according to the pre planned process curve, and precise process control ensures that the coil has no pores or voids.
The low-voltage coil adopts a foil structure, effectively solving the problem of unbalanced ampere turns in the wire winding type of low-voltage and high current coils. At the same time, the foil coil does not have axial turns or axial winding helix angles, effectively eliminating the axial force of the transformer during short circuit, ensuring that the current density inside the coil can be freely adjusted along the axial direction according to the load distribution of the high-voltage coil, and reducing the radial force during sudden low-voltage short circuit. The end of the wound coil is sealed and cured with resin to prevent the entry of various foreign objects and moisture.
Usage conditions:
The use conditions that meet the following requirements are normal use conditions:
a. Altitude
The altitude shall not exceed 1000m
b. Environmental temperature
Maximum temperature+40 ℃
Maximum daily average temperature+30 ℃
The highest annual average temperature is+20 ℃
Minimum temperature -30 ℃ (applicable to outdoor transformers)
Minimum temperature -5 ℃ (applicable to indoor transformers)
c. Waveform of power supply voltage
The waveform of the power supply voltage resembles a sine wave.  
d. Symmetry of Multiphase Power Supply Voltage
The power supply voltage connected to the multiphase transformer should be approximately symmetrical.
Application scope:
The product's strong ability to withstand thermal shock, high overload capacity, flame retardancy, high fire resistance, insensitivity to humidity and dust, and other advantages have created its wide adaptability. It is most suitable for use in harsh environments with high fire prevention requirements, large load fluctuations, and dirty and humid conditions. For example, it is suitable for important or special environmental places such as high-rise buildings, commercial centers, airports, tunnels, chemical plants, nuclear power plants, ships, etc.
